-----------------------------------
Summary: throttling_test fails if the producer starts too fast.
Key: KAFKA-4558
URL: https://issues.apache.org/jira/browse/KAFKA-4558
Project: Kafka
Issue Type: Bug
Reporter: Apurva Mehta
Assignee: Apurva Mehta
As described in https://issues.apache.org/jira/browse/KAFKA-4526, the
throttling test will fail if the producer in the produce-consume-validate loop
starts up before the consumer is fully initialized.
We need to block the start of the producer until the consumer is ready to go.
The current plan is to poll the consumer for a particular metric (like, for
instance, partition assignment) which will act as a good proxy for successful
initialization. Currently, we just check for the existence of a process with
the PID, which is not a strong enough check, causing the test to fail
intermittently.
